Confused...

Tr
Sorry if this gets long...
Here's my story. I'm 23 with a 5 yr old, if you do the math you'll see I got pregnant pretty early in life. My family has been 100% supportive of my son and I. I graduated high school early with a 4.0 before my son was born and started college right after that. 
Well over the years I took classes on and off changed my major several times. On top of caring for my son and working full time. Right now I am living with my grandma until I pay off some debt to move out.  I have lived on my own before but I had to move back in with my grandma after my bf left for the navy and I couldn't pay the bills on my own. 
I'm taking one class now and still undecided on what I want to do as a career. My grandma can get verbally abusive and idk how much longer I can live with her. 
My question is what are some ways I can make some extra cash or does anyone have any experience with trade schools of some sort? She's pressuring me to take out loans and go to school full time while living with her on top of working. And I just want to leave.  I just want a better life for my son and I.
